玉米漿幹粉中微量元素的測定

玉米漿幹粉是由玉米漿經即時加熱，噴霧幹燥制成的，可以廣泛用于發酵行業，例如抗生素，維生素，氨基酸，酶制劑等。當前，與醫藥和食品有關的各個行業越來越關注原材料中重金屬元素的含量。但是，尚未報道測定玉米漿中重金屬元素的方法。電感耦合等離子體質譜法（ICP-MS）是一種靈敏而有效的元素分析方法，尤其是同時分析低含量和多元素的方法。

ICP-MS测定了不同厂家玉米漿幹粉粉制品中As，Cd，Cr，Cu，Pb，Se，Zn等七个元素的含量，为测定食品中玉米漿幹粉和一般生物样品的重金属含量提供了一种简单可靠的分析方法。

通過測量不同生産廠家的樣本分析表明，大部分元素的含量基本接近，但是Cr元素的含量差異較爲明顯。猜測可能與生産過程中使用的不鏽鋼器皿質量有關。通過采用ICP-MS技术测定了其中元素的含量，并通过对比得出这个方法是测定玉米漿幹粉以及一半生物样品中的重金属元素的一种线性范围宽，精密度高，简便可靠的方法。

我司生产的玉米漿幹粉采用优质新鲜玉米浆，玉米浆在使用前，会经过去除杂质、研磨、洗涤，然后将不溶性杂质去除，再采用蒸汽低温喷雾干燥，产品无焦化、糊化现象，有效成分未破坏。关于玉米漿幹粉中微量元素的測定的相关内容就先为大家介绍到这里了，希望对大家有所帮助，还有关于玉米漿幹粉的有关问题欢迎随时咨询。

ALLAHABAD “Larry, they’ve spotted that-there boat,” Jeff spoke through the tube to the young pilot. “Yep. More to the left. That’s it—both at the same time! Stick to the left, rudder, too. Good boy. Now the stick comes back to neutral. Hold her as she is—better cut down the throttle a little as we bank and turn to the left.” There was a bright I. D. blanket spread on the ground a little way back from the fire, and she threw herself down upon it. All that was picturesque in his memories of history flashed back to Cairness, as he took his place beside Landor on the log and looked at her. Boadicea might have sat so in the depths of the Icenean forests, in the light of the torches of the Druids. So the Babylonian queen might have rested in the midst of her victorious armies, or she of Palmyra, after the lion hunt in the deserts of Syria. Her eyes, red lighted beneath the shadowing lashes, met his. Then she glanced away into the blackness of the pine forest, and calling her dog to lie down beside her, stroked its silky red head. The 200th Ind. was raging along the foot of the wall, trying to find a cleft in it by which they could climb to the top and get at their foes. Standing a few yards in the rear, under a gigantic white-oak, whose thick branches promised protection from the crashing bowlders, the Colonel was sending parties to explore every place that seemed hopeful, and report to him. When Si came up with his squad he was directed to go to the extreme left, and see what he could find. "Give me that bandage," said the Surgeon just before he hurried away. "Take this sticking-plaster and draw the lips of the wound together, and if you keep the dirt out it may heal without a scar." As they headed toward the big front doors others followed, but there was no use bothering about that. When Cadnan opened the door, in fact, the others fell back and remained, staring, until it had shut behind them. There was the great noise of bells and buzzers—but that had been going on, Cadnan realized, even before they had begun. Outside, the spot-lights seemed weaker. There was smoke everywhere, and ahead the forest was a black and frightening mass. "No, to me." "Perhaps she'll get you before then." HoME 色先锋草莓av天天日ENTER NUMBET 003www.angangxi.com.cn
